Outsmart the hunted

From a pair of Dallas-raised outdoorsmen, this new app taps GPS, current date/time, and U.S. Naval Observatory astro-data (tides, sun/moon rise and set...) to give users geographically specific recommendations on the absolute best times to pursue a variety of game, "whether you're hunting for trophy whitetail deer in South Texas...or on a photo safari in Kenya" -- with the beast-tracking all taken care of, your guide will be free to haul your espresso machine.
